• Abstract: The evolution in the resin infusion process is due to cost reduction, environmental regulations and the high quality of composites manufactured using these techniques. The resin infusion process essentially consists of using vacuum pressure to flow the resin through layers of dry materials (placed in a mold and covered by a vacuum bag) through carefully placed pipes. Once an infusion has started, little can be done to correct any errors; which normally lead to the total loss of the piece. For this reason, experience is acquired through a process of trial and error. Therefore, here we present a review of the available knowledge, techniques and matrices used, as well as a review of the state of the art on what has been done regarding the techniques used and properties obtained in composites with the inclusion of natural fibers.
